I haven't heard that as far as I know I believe Microsoft confirmed they don't control EPIC which insinuates it might be Multi-Plat. If it is though then that's pretty awesome for Sony to literally flip an exclusive.
It's already out, the only massive issue is that I haven't recently been able to play on any online matches.
I followed my buddy and we both bought premium at the launch of the PS4. I really hope for the supporters like us I hope they will reward us.
